RAMANRXN1 Microprobe

RAMANRXN1 Microprobes uses advanced and innovative technologies to provide distinct advantages over other available instrumentation. 785-nm excitation is available as standard to minimize fluorescence and maximize sensitivity. This compact system includes our award-winning axial transmissive imaging spectrograph design featuring fast ƒ/1.8 optics and our HoloPlex™ transmission grating technology. The HoloPlex™ advantage provides wide spectral coverage and high spectral resolution simultaneously for improved qualitative and quantitative analysis. The entire Raman spectrum is collected simultaneously at high resolution by optically folding the scattered Raman photons onto a large-format multichannel CCD detector. Qualitative analysis is faster compared to traditional scanning instruments because all the wavelengths are measured simultaneously. This unique advantage also allows for more accurate quantitative analysis, which is especially important for chemically changing samples (e.g., polymerizations, curing) or species with widely separated analytical bands of interest.

Fiber optic coupling provides real experimental versatility and stability and allows for future system upgrade. The RAMANRXN1™ Microprobe is ideally suited for method-development work, routine troubleshooting, or materials characterization. Simply switch fiber optic cables to go between the microprobe and a remote sampling setup without instrument realignment. The optional calibration accessory provides an easy-to-use calibration and validation protocol and ensures optimal instrument performance. This protocol provides analytical robustness during method development and instrument documentation for regulatory purposes.
